my question is. i installed a oil catch can and its not catching any oil at all. bone dry, there is no oil anywhere in the places it would build up as well (intake tube, turbo inlet, compress hot side pipe) ive ran the thing for 1000 miles or so. when i took it all off the problem came back. black oily sludge everywhere it used to be. it dosent appear to be clogged the hoses dont look oily. so wtf. any thoughts here is a pic of my set up.

i use the corvette, camarro elite engineering catch can. it has a baffle as well

 

nice intro haha

 

nvm

engine pic is **** btw

 

Well, you still have your original PCV tube hooked up to the intake, so I'm trying to figure out where your inlet and outlet for the catchcan is coming from.

 

Nice engine bay!

 

i dont know what nvm stands for sorry if thats noobish and what dose engine pic is **** mean were u trying to say its tight or something. sorry

 

He means he likes it.

 

the catch can is hooked up to the back of my valve cover and the inlet tube to the turbo. the other braided hose your seeing can only draw air from the intake into the valve cover it cant blow. but the back of the valve cover is free flowing so when there is pressure the vac from the turbo and intake relieves that pressure. thats why u get oil there down in the intake pipe

 

iam baffled by this. i though i would have seen oil by now. i have it hooked up right. thats how the mpx catch can goes in iam sure, so whats the problem 1000 miles no oil take the can off and after one tank of gas i have drops siting at the bottom of the turbo and there is residue in the hot side pipe. its just weird

 

this is what i think is happening. let me know if u think iam crazy. maby the oil isnt condensing in the can and since the oily air has to travel a longer distance cause of the extra tubing that its just not condensing onto the usual places in the turbo and intake and the engine is just burning the oily air.

 

in for reslults

 

Elite Engineering makes great products. I've bought a lot of their stuff. As to why it isn't working on your Cobalt, I'm afraid I can't help much there.

 

Pretty sure you have the catch can in the wrong line.


From the MPx site for their catch can...

Keep your intake piping clean and free of oily residue with the MPx Oil Catch Can. By intercepting the breather hose from the valve cover this unit will accumulate and collect oil that would other wise end up as intake sludge.

 

how come 2 people are saying i have it on the wrong line. i have it hooked up exactly how the mpx catch can is hooked up. there is no oil anywhere in the system like IAM BROKE is saying. its dry everywhere and when i take the can off and put back the line i took off i get oil within a tank of gas

if u unhook the bradded line and try to suck on it. the valve closes and u cant get air if u blow into it u hear the air go into the valve cover. iam going to try and find a pic of the mpx catch can on someone's car here and show u that i have it hooked up right.

 

maybe this will help even though its a cheap one.

here is how NORTH VIBE did his and a few otheres

 

Guess I remembered wrong then, oh well. <shrugs> I never needed to run one.

 

i know i hooked it up to the right spots. the reason why the bradded line is there is if the motor is under vacuum or negative pressure it can suck air in from that line. the line that connects from the back of the valve cover to the turbo is where the blow by goes. i think the bradded line is also there as well to circulate the air in the motor. the turbo creates a low pressure and sucks the air out of the motor from the back of the valve cover into the intake track and the braided line feeds it new fresh air

this guy hooked it up right to but i heard that u shouldnt use those cobalt air compressor water catchers few people got clogged up and thats no good. then u start blowing oil through seals cause it cant vent pressure.

its funny how there called cobalt.

 

Its hooked up right, remember no oil is a good thing, not every car is gonna blow oil out like a sieve.

 

iam glad there is no oil but at the same time i wish my 170 dollar investment would at least be catching something. i guess iam going to keep running it and see if it ever dose catch anything.

the point of the thread was to see if anyone had any ideas why it would all be bone dry after 1000miles with its on and when i replace the factory line back on that it gets oil in there after 1 tank of gas.

 

Perhaps the longer lines and the restriction of the flow through the baffled can is slowing down and reducing the amount of airflow so you don't carry any oil through.

 

ha ha, bs, i got mine hooked up to that one and it catches oil, very little, but it does. but we have very little blowby on these cars, so it takes a while to get any, in winter ull get alot of oily condensation though

 

I was under the impression that this was the correct way to run the lines.....don't know for sure though....but i need to find out cause my mpx unit will be here shortly

 

Is it possible that with the tank in there it has lowered the vacuum pressure from the valve cover to the intake? Maybe when the shorter stock tubing is on there is more pull from the intake and its able to pull more oil vapor from the top end of the motor?
